So this story unfolded with a few twists and turns… and I’ve reached a stuck point…
I ordered an SD card… I couldn’t get my Mac to recognise it?

(Perhaps mounting issues as opposed to faulty card)
Tried to see if I had SD card slot on telly to test… didn’t… so decided to pop it in the Wii… where I discovered…
There was already an SD card in the slot! And I managed to format my external hard drive with the Wii u and transfer the games that were on the SD across
Since then I felt things were a little messy/uncertain, so decided to reformat the wiiu and do Haxchi then CBHC install on my own profile with a DS exploit- which I did successfully
The problem I have no is that the external hard drive has to be reformatted again to be recognised by the Wii u after the system reformat and new exploit installation
Ordinarily I could just use Wii usb helper to download the game files again; but I’m on a Mac and don’t want to have to run wine or virtual pc or put windows anywhere near it. I also don’t have access to another persons pc to be able to use it.
I’ve managed to find 7s files- and I used something called Keka on my Mac with them which made them cdr files, which I could create an iso from with disc utility; but then the issue I have is that they’re huge and can’t go across on my SD card as because of the fat32 format it needs to be under 4gb
I also managed to have .wux files, but they need to be converted to .wbfs which requires a pc converter tool to be able to do so. I haven’t found any Mac software that could do it.
Some games I have as physical copies and can put them cross to my external hard drive, but the file sizes are huge… but there are games I really wanted to play that I’ve just simply lost
This has been quite a headache. There’s progress, but there’s also the loss of games which is a big issue. Can you help at all?
Thanks for your help and things look on the up!
